Gear ratios dont play a part in where you shift as much as your saying(manuals only). It does, but not to the extent your saying. Alot of it plays in where your cam lobes are ground to. Not sure if any of you come from a background in old school 350"s and 302"s but going beyond your peak hp to far is not good. My 1971 Chevy truck has a nice 350 4bolt main that runs like a bat out of hell until i go to far into the rpm range and the cams begin to "float". This can and will happen if you go to far up the tach. Another words you are wasting time being up to far in your rpm range because your not gaining speed(you are but not as much). I dont know, it all really depends on so many variables you cant say specificly where to shift. Thanks for the info, this just proved to me the Honda Forum has alot less motor head gods that think everyone else is wrong but them. Thanks for not banning me
